Specification of Letters Patent.

Patented May 15, 1917.

To all whom it may mum/vi Be it known that l. Tirtnmoi's Y. inliio'rr, aomzen of the l'mted States. and a resident the city of New lfork. borough of Man hattan, in the county and State of New York, have ini'entcd a new andfln'iproved.. Tire. of which the following is a folk clear and exact ilescription.

The invention relates to pneumatic tired ivheelslur automobiles and similar vehicles having a shoe and an inner tuhe.

The Ul) ('t of theinvention is to .provnle a new and improved tire arranged to per unit conyenient removal oi the tread ivhen worn out. and replacing the same by a new one to prevent puncturing oi the shoe. and

inner tuhe and to relieve the shoe of all undue strains.

In order to accomplish the desired result, use is made of a tread removalal overlying the peripheral face of the shoe of the tire,

and a fastening device permanentlr' associated with the tread and having side menihers reniovahly engaging the rim of the wheel.

A practical enil'iodilnent of the invention is represented in the accompanying drawings forming a pal-tot this specification, in which similar characters of reference indicate corresponding parts in. all the views.

Figure 1 is a side elevation of the tire as applied to a. portion of an automobile Wheel;

Fig. 2 is an enlarged cross section of the same on the line 2- 2 of Fig. 1;

Fig. 3 is a plan view of the removable tread with part in section on the line 3--3 of tied forinof the removable tread;

Fig. 6 is an enlarged. cross section of the same on the line 6-4; of Fig. 5; and

Fig. 7 is a cross section of a modified, form of rim.

An inner inflatable tube 10 is inelosed in a shoe 11 attached in the usual manner to the rim 12 ,of a telly 13 of an automobile or other vehicle wheel. The peripheral face of the shoe l1 is overlaid by a removable rubber trcarll4 having a base. 1'5 and spaced blocks [6 rising integrally from the, said base 15. The outer face, of each block 16 is provided with recossesl'i, of various shapes, as shown channel ring 25.

" tread H is embedded a transverselyextending member 20 terminating in eyes 21 exterior of tlicisides ot' the tread 1%. preferably at the Pllltlfillfi between the adjacent ends of successive blocks 16'. as plainly indicated in the drawings. The eyes 21 at' each side the tread are connected with each other by longitudinal inenihers fitting against the eorrespoinling sides of the tread 14:. Froih lilt'll ol the eves 21 extends a flexible member '23. preterahlv in the form of a chain, dis,- posed radially and overlying the corresponding side of the shoe 11. Each of the flexible members 23 terminate at. its inner I end in a hook 2+ engaging a channel ringQEjfi'. which may form an integral 'part'of the rim 1?. asshown in Figs. 2 and- 6. or a removable.

1m rt as illustraQ d injFigT. The terminal 26 of each hook Qiis enlarged and fits a cor respondingly shaped channel in the 'ring 25 so thatthe hook 24 is not liable to become accidentally detached from the channel ring The channel ring 25 is provided with 85. one or more notches 27 (see Fig. 1) to permit of conveniently passing the enlarged end 26 of the hooks 24 into the corresponding It is understood thatafber an enlarged end 26 has passed intothe channel ring 25 the tread and its attaching means are shifted on the shoe 11 to move the/hook away from thenotchos 27 and to allow of 1 engaging the hook successively with the notches 27, for engagcmentwith the channel ring 25. It is understood-that the tread is attached to the shoe ii at thetime the tube 10 is deflatedto'perinit convenient engagement of the hooks EH with the-channel ring 25, as above explained. and then the inner tube 10 i inflated to extend the shoe 11 and to draw the {lexihle members 23 taut on both sides of" theshoe. ll'hen it is desired toremove the tread 1 1 for rerdacing it h a new one in case it worn out or for other purposes, then the tube 10 is deflated. a lter which the tread is shifted relatively to the, tire'll to ln'ing the hooks 2 L successively into register ivith the notches 27' for disengaging the hooks from the channel ring '25. 11.

Thetransverse members 20 and the longitudinally connecting members '22 may be made in -'ai'ious shapes; for instance, as

shown in Figs. 2 and 3, the transverse members 20 are made of wire twisted together at intervals and forming squares between adjacent twists, the side corners of the squares terminating in the eyes 21. It will be noticed that this member "20 strongly reinforces the tread 1% and at the same time forms a convenient means for attaching the connecting members 22'and the radial n'lenibers 23 to the e ves 21.

As shown in Fig. 4, the transverse members 20 and the. side members 22 are in the form of rectangular frames embedded in the tread 14 and provided at their corners with the eyes 21 for engagement by the outer ends of the radial members 23. v

In the modified form shown in Fig. 5, the transverse members 20 are in the form of plates terminating ineyes 21 engaged by the side members andthe radial members 2 -5.

From the foregoing it will be-sccn that by the arrangement dcscribmh the tread is refmovably attached .to the peripheral face of the shoe and can be conveniently placed in position or removed whenever it is desired to do so.

-It will also be noticed that by the construction above set forth the tread is strongly reinforced and it relieves the sh oe of all undue strain as the connection ofthe tread is with the channel rings'25 ot' the rim of the wheel.

It will. further be noticed that the connecting eyes :21 are located between adjacent blocks 16 to give the tread thev desired resiliency when pressure isapplied and with out unduly bending-the reinforcing members.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a pneumatic tired wheel, a tread ha ing eyes at its sides, chains having hooks at their ends. the hooks at the outer ends engaging the eyes, the hooks at the inner nds of the chains having enlarged ends, and a rim having longitudim'il channel rings at its sides with which the said lower hooksen' gage the channel rings being notched to permit the engagement of the said hooks with
